1M PROVEM ENT IN WATER-ELEVATORS.

. Specification Aforming part o f Letters Patent No'. 35,578, dated June 17, 1862.

To all whom `it may concern: n

n Beit known that-I, STEPHEN L. AVERY, of

Norwich, in the countyof Ghenango-and State of New York, have invented a new and Improved --Apparatus for Drawing Water out of Vells and Cisterns; and I do `hereby declare that the following is a full and exact description thereof, reference being'had to the accompanyingdrawings, which form a portion vof this speciflcal'lion`` `Figure lis a top viewof said apparatus; Fig.- 2, a side ,View of the same; Fig. 3, an end View; Fig. 4, a section in the line y y of Fig..

`1; Fig. 5, a section in the line :v x of Fig. 2;

andf thereniaining drawings represent de tached portions of said apparatus in detail.

l Similar letterswindicate the'same parts in each of the drawings.` Y

The corner-posts A A, the"cap-pieces B B, which `surtnount thesalne, and the planked sides which unite the said `crier-jiiosts form the supporting-frame of my improved waterdrawing apparatus, at the same time that they form the inclosing-curb of the well or cistern.v

The journals ofthe windlass-shaft C are revceived into the journal-boxes I J, which are bolted to the frame cap-pieces B B.. The journal at theQright-hand end'of the windlassshaft is elongatedfor the purpose of enabling it to receive the outwardlyopening cylindrical head a E and the inwardly-opening crank-head D, as

represented in the drawings. The head E,

' which is rigidly secured to the Windlass-shaft,

isl composed of the disk E, the outer tubular iiange, a, "and the interior ratchet-wheel, b, which project from the outer face of said disk.

The crank ratchet-head D consists of an outer disk andan inwardly-projecting tubular l iiange from the periphery of the same, the said flangehavin g ratchetteeth formed `on the outer periphery'of the same. -The respective sizes of theouter periphery of the tubular flange a of the head 4E andthe inner periphery of the ratchet-ange of the head D are such that the latter can pass freely and loosely over the face of the former, as shown in the drawings.y n

The crank F has a pivot-hole, fi, and also two short branchingarms, j and k, which project outwardly from the said pivothole, as`

shown in Fig.7.i,"The crank F is jointed to the ear t, which radiates from the periphery of the head D. flhe outer end of the elongated l ten t, c,

journal of the windlass-shaft fits loosely within the central aperture of the `head D when the said head is combined with the head E.

' The manner of retaining the head'Din `its n connection with the head E'is clearly repre sented by Figs. 2 and 5 of the drawingsviz;, the: forked holder g is pressed into an annular groove near the end of the elongated journal of the windlass-shaft by means of the spring h, which rises from the cup f, that is formed atA the extremity of the branch arm j of the crank,

the said forked holder being also additionally .supported by means of an inward projection therefrom, which passes into the slot e, Fig. 6, in the face of the ratchet-head D; A dein Fig. 4.

The hook-headed pawl n, which engages with the ratchet-teeth of the head D, is pivoted to the outwardly-curving arm m, which rises from the journal-box J, the hook-head of said pawl gliding smoothly over the ratchetteeth of the head' D while a forward Inovementis being imparted to the windlassshaft.

After the bucket H has been elevated to the `proper height, and its contents have been discharged 'in any suitable manner,the crank can be uncoupled fromthe head E of the windlassshaft by simply pressing backward the crank against the resisting action of the pawl n with sufficient to force to iirst overcome the action of the spring h upon the crank, and then to draw the detent con the branch arm k of said crank beyond the reach of the teeth of the ratchet-wheel b of the head E; but the instant that the ratchet-tooth c is drawn lbeyond the reach of the teeth of the ratchet-wheel b, it strikes against the inner periphery of the annular flange a of the head E, and consequently but a moderate degree of force need then be projects from the inner side of the rior` ratchet-wheel, b, of the head E, as 'shownl e exerted upon the crank to produce a degree of friction between the surfaces of the said ratchet-tooth and Hange to perfectly control and regulate the descent of the bucket into the well or cistern; and as soon as the crank is relieved of the aforesaid backward pressure the action of the spring h thereupon will throw the ratchettooth or detent c again into connection with the ratchet-wheel b of thehead E, when the windlass will be ready for another forward movement.

It will be perceived that the spring h serves two important functions-viz., in connection with the forked holderg and an annular groove near the end of the windlass-shaft C, the said spring serves to couple the head D with the head E, which is rigidly secured to the windlass-shaft, and in connection with the forked holder g and the branch army' of the crank, the said spring serves the purpose of retaining the ratchet-tooth c of the branch crank-arm 7c in connection with the teeth of the ratchet-Wheel b of the rigid head E of the windlassshaftduring the forward movements that may be imparted to said shaft. It will also be perceived that the forked holder g can be easily detached from its hold upon the end of the windlass-shaft whenever it may be desirable to detach the head D from its connection with head E.

Having thus fully described my improved apparatus for drawing water out of wells, cisterns,&c.,whatI claim therein as my invention, and desire to secure by Letters Patent, is-

l. rlhe annular outer ange, a, and the interior ratchet-Wheel, b, which respectively project from the outer face of the metallic head E of the windlass-shaftiwhen the said parts have substantially the proportions and are used in the manner and for the purpose herein set forth.

2. The jointing of the branched crank-lever F with the movable head D, when the said head is combined with the rigidly-secured head E ofthe windlass-shaft, in such a manner that the ratchet-tooth c on the branch arm 7c of said crank-lever can be made to operate in conjunction either with the ratchetwheel b or the annular flange a of the aforesaid head, in

the manner herein set forth.

3. The arrangement of the forked holder g, the spring 7L, and the branch arm j of the jointed crank-lever F with each other and with the head D, and the annular groove near the end of the windlass shaft, substantially in the manner and for the purpose herein set forth.

4:. Thearrangementof the hook-headed 'pawl n with the metallic head D when the said head is jointed to the branched cranklever F, and when these said parts are combined with the head E of the windlass-shaft, substantially in the manner herein set forth.

The above specification of my improved apparatus for drawing water from wells, cister-ns, Ste., signed and witnessed this 27th day of March, 1862.

STEPHEN L. AVERY.
